UNITED STATES LUC HOUZE, OF MEADVILLE, PEUNSYLVANIA.

APPARATUS FOR FLATTENING WINDOW-GLASS.

SPECIFICATION forming part of Letters Patent No. 336,855, dated February 23,1886.

Application filed August 18, 1883. Serial No.l04.1i0. (No model.)

T all whom, it mag concern:

Be it known that I, LUo Ho'uzn, a subject of the King of Belgium, residing at Meadville, in the county @of Crawford and State of Pennsylvania, have invented certain Improvements in Apparatus for Flattening \VindowGlass, of which the following is a specification.

The invention will first be described in connection with the drawings, and then pointed out in the claims.

In the drawings, Figure l is a horizontal section; Fig. 2, a vertical section through line a a of Fig. 1. Fig. 3 is a detail view, in side elevation, ofthe car preferably employed. Fig. 4 is a detail view, in elevation, of the table and its support. Fig. 5 is an end view of one of the leer-rollers in its hanger. Fig. 6 is a longitudinal vertical section through the leer. Fig. 7 is a transverse vertical section through the leer. Fig. 8 is a horizontal section showing the guides by which the plate-support is held in place while being lifted.

1n the drawings, A represents the gasgenerator; B, the glass-flattening chamber; 0, a

cooling-chan'iber separated by a hanging wall, I, therefrom; D, the leer, and E rods connected at the outer end by a cross-bar, ll, and arranged to slide in the-leer-rollers G, as well as be raised and lowered in taking the glass from the cars and through the leer.

F is a turn-table having two parallel tracks, Zr, on opposite sides of its center, so that one may be in the flattening-chamber while the other is in the cooling-chamber C. Corresponding track, k, registers with either of the tracks It and leads to the leer.

H represents the flattening-stone, which is provided with holes I), through which pass the pins 1), (shown in Fig. 6 of the drawings) and whose supporting-plate ill is raisedby plate I, which is operated by the mechanism b b b b. Thus it will be seen that all the pins are raised together, so as to elevate theglass.

N represents the axle of turn-table wheels, car-wheels, and leer-rollers, and these axles are made to roll withinthe slots, oblong spaces, or bearings 0, so as to avoid as far as possible too great an elevation of temperature by close axle-boxes.

I connect the furnace Awith the flatteningchamber B by the channel 0, so that the gas is carried while at a high heat to chamber B, where it is burned over the flattening-stone H, and the glass cylinder or roller heated sufficiently to be flattened on said stone. The table is then turned to bring it around into the cooling-chamber C, while a second glass cylinder or roller is brought into the flatteningchamber and placed upon the empty car on the other track and by the change of position in the turn-table. In this manner the work proceeds, one glass being in the flattening and onein the cooling chamber all the time. After leaving the cooling-chamber the car carries the glass over track 7.1 to the mouth of the leer which connects with the cutting-room. When the car has arrived in the leer-mouth, as shown in Figs. 1, 2, 6 of the drawings, the pins I) are lifted by the plate M and its operative mechanism P b b b (1 so as to raise the glass above the stone H. and allow the bars E to be pushed under the glass, but without touching it. The leer-rollers G are then raised byrnechanism cl d d d d d and lift the bars E, taking the glass from the pins 1/. Then the bars E are drawn back and letdown into grooves on the leer-bottom, leaving the glass supported on fire-brick. The same operation is repeated with every glass cylinder in succession. The glass is thus thoroughly cooled and annealed before it is taken ofi' the bars at the back end, which is open in practice. By my invention I flatten the glass much more rapidly than has been done up to this time.

The use of pins, instead of the usual fork employed, prevents the scratching and fracture of the glass as well as the rubbing of small pieces from the edge.

As the axles and their boxes are exposed to great heat, lubricants cannot be employed in glass-flattening furnaces with any advantage, and hence the ordinary bearings work with a great deal of friction. This is to a very great extent obviated by my oblong or slotted bearings c, on which the axles roll back and forth. By'dispensing with solid fuel in the flattening chamber and connecting the chamber B directly with the gas-generator, so as to bring the gas thereto, I prevent the glass from being affected by impurities in the products of combustion, and am thus able to give it a very superior luster. I can also in this way utilize all sorts of fuel in manufacturing the gas. and thus considerably lessen the expense of heating.

I hereby disclaim as any part of my inven-- tion'the following: In the leer of a glass-flattening apparatus, the combination of crossshafts G, having journals, and side walls having slots or elongated bearings for said joun nals, as set forth.

Having thus described all that is necessary to a full understanding of my invention,what I consider new, and desire to protect by Letters Patent, is-

1. A glass'flattening apparatus in which a heating-chamber, B, and cooling-chamber G are separated by a hanging wall, I, and have on their floor a turntable, one lialf of which is in each chamber, as and for the purpose set forth.

2. In the leerofaglass-flattening apparatus, the combination of the rods E and rolling cross-shafts G,with lifting mechanism in which spaces 0 c are provided for the journals of said shafts, substantially as set forth.

3. The flattening-stone H, having holes I) and pins 11, in combination with asupportingplate, M, adapted to be raised or lowered, as and for the purpose specified.
